Hey HanFox, do you think you could add arrows on the top and sides of hoppers in the technology add on pack thing to show where the items in the hopper will travel? maybe even turn it into an X if the hopper is powered?

https://xisumavoid.com/vanillatweaks/ has Directional Hoppers, at least on top under "Utilities". Even if directions are only on top of the hopper, it would be a huge help. Slimy piston sides might also be a good one for the Technology pack.
